What are the materials for exterior wall insulation? and construction technology

What are the exterior wall insulation materials? Six key points of construction.

Exterior wall insulation materials emerge in endlessly, and everyone is dazzled, so let's talk about it for you today, what are the common exterior wall insulation materials, and some construction points.

Common materials. Common exterior wall insulation materials include polystyrene foam board, extruded plastic board, rock wool board, polyurethane board, aluminum board, thin ceramic composite board, etc.

Construction points. 1.Choose the right material: Choose the right exterior wall insulation material according to the wall structure, wall material, environmental conditions and other factors.

2.Ensure that the base layer is dry and clean: before construction, it is necessary to ensure that the base layer of the wall is dry and clean, and remove oil and dust.

3.Ensure that the construction level is uniform: the material level should be uniform during construction to avoid omission or reapplication.

4.Ensure the quality of construction: Attention should be paid to quality control during construction to ensure that the adhesive of the insulation material is firm.

5.Avoid the phenomenon of thermal bridges: In the construction process, it is necessary to pay attention to avoid the occurrence of thermal bridges, especially in the parts of doors and windows, balconies, rainwater pipes, etc., and select appropriate thermal insulation materials for construction.

6.Ensure fire performance: Exterior wall insulation materials should have good fire performance to ensure the safety of the building.

Exterior wall insulation materials are: polystyrene board, that is, foam board, extruded board (foam board upgrade product), rock wool, glass wool, polyurethane, etc., the above are the most commonly used wall insulation materials.

Construction technology: plate + mortar + nail + mesh cloth.

We have exterior wall insulation products and construction technology here to take a look, I hope it will be helpful to you.

Winters are cold, especially in the north, and when winter comes, people put on thick winter clothes to prepare for the winter, but who knows how the house survives the winter? If the house is not well insulated, it will seriously affect the service life of the building, and if the insulation is not good, the heat loss will be more, and the indoor temperature will not be high. In fact, the insulation of the house mainly considers the insulation of the external wall, so how to insulate the external wall, or what the insulation material is is a problem that should be concerned.

Generally speaking, the external wall insulation can be made of polymer mortar, fiber mesh cloth, phenolic foam or polystyrene foam board (EPS) or extruded plastic board (XPS) and other materials, and the foam board should be made of flame retardant, which is bonded on site.

The second point about how to insulate the exterior wall is to choose the correct construction process with socks, and the normal ambient temperature of the old worker is 5 35 when doing the external insulation of the exterior wall. Moreover, within 24 hours after the completion of heat preservation, the temperature must be ensured to meet the requirements, the wind force cannot exceed level 5, and the temperature cannot be exposed. The erection tools and scaffolding used in construction should meet the needs of construction safety.

The distance between the high-voltage wire and the construction site in the construction operation environment should comply with the relevant regulations, and there must be corresponding protection facilities.

The third point about how to insulate the exterior wall is to choose the correct construction process, in which the use of reasonable anchorage is a very important one. To fix the polystyrene board, the anchor installation should be carried out at least 24 hours after the use of the mortar, and the anchorage depth should meet the design requirements.

Finally, the treatment of how to heat the exterior wall is the choice of the outer wall protective layer, you can use a thick protective layer of 25-30mm, or you can choose a thin protective layer with a thickness of 10mm, in order to reinforce, you can use a diameter of 2mm, 50*50mm steel mesh, so that the protective layer will be stronger.

After introducing the question of how to insulate the exterior wall and the selection of insulation materials, I believe that we will no longer be unfamiliar with the content of external wall insulation, and we can buy excellent quality insulation materials, so that there is a warmer and more comfortable indoor space environment in winter.

High-quality exterior wall insulation boards should have the characteristics of no harmful substances, low carbon and environmental protection, etc., which can reduce environmental pollution.

5.**: The external wall insulation board is also one of the factors to consider when choosing. Different types and brands of exterior wall insulation boards are different, and they need to be selected according to the actual budget.

In short, the selection of exterior wall insulation board needs to comprehensively consider the above aspects and choose the right product for yourself to achieve the best thermal insulation effect.

In this cold north, keeping warm is the work we have to do, whether it is our own warmth or the insulation of the house is what needs to be done, so the materials in the home decoration are also insulated, and the house will not be so cold with insulation materials, thenExterior wall insulationWhat are the types thereof? What are the precautions for the construction of exterior wall insulation materials? Let's introduce it to you.

First, the types of exterior wall insulation materials.

1.Fiberglass insulation foam.

Glass fiber wool is an inorganic non-metallic material with excellent performance, and it is also one of the three common interior wall insulation materials. The diameter of the monofilament is a few microns to more than 20 meters of microns, which is equivalent to 1 20-1 5 of a hair, and each bundle of fiber precursors is composed of hundreds or even thousands of monofilaments.

Board. It is the abbreviation of expandable polystyrene board, which is developed by the expandable polystyrene material through pre-hairing, curing, drying and cutting technologies. This kind of exterior wall insulation material can not only be made into foam plastic products with different densities and shapes, but also can produce foam boards of different thicknesses.

3.Polystyrene foam board.

Polystyrene foam board is one of the three common interior wall insulation materials. Also known as foam board and EPS board, it is a white object formed by heating the expandable polystyrene beads containing volatile liquid foaming agent and heating them in a mold. It has the structural characteristics of fine closed cell, and is mainly used for building walls, roof insulation, composite board insulation, etc.

Second, the construction of external wall insulation materials precautions.

1.During construction, it should be noted that materials should be classified and listed for storage. Polystyrene boards should be placed in bundles to prevent rain and moisture.

Mesh cloth should also be stored in the rain. The storage of bonding and plastering mortar should also pay attention to rain, moisture and shelf life. The temperature of the operating site environment and base layer shall not be less than 5.

Wind force greater than 5 or rain cannot be carried out. If there is sudden rain during the construction of external wall insulation, effective measures should be taken to prevent rainwater from washing the wall.

2.The exterior finishing layer should be painted (or colored mortar), and the insulation layer in the system is mostly a lightweight porous material with low shear strength, so the facing layer should not be used as a brick. For example, there must be reliable measures to prevent the bricks from falling off and injuring people.

The surface of the Yitong insulation system is reinforced with a protective layer, which has high strength and excellent impact resistance.

Nowadays, there are many buildings that will use insulation boards, especially in residential areas, so what are the types of rental high-loss wall insulation materials and what are the precautions for its use, I think you have also understood it through the above introduction.

With the improvement of living standards, people have higher requirements for home decoration, not only to be beautiful and comfortable, but also to have the characteristics of thermal insulation and waterproofing. So what are the exterior wall insulation materials on the market? What are the advantages and disadvantages? Let's take you to find out!

1. What are the external wall insulation materials - mesh cloth.

Mesh cloth, also known as glass fiber mesh cloth, is mainly based on medium alkali or alkali-free glass fiber mesh, and then dried by acrylic acid copolymer solution to form a new alkali-resistant product. It has a stable structure, high strength, good alkali resistance, and simple and fast construction. It is mainly suitable for the use of cement, gypsum, and wall buildings.

2. What are the external wall insulation materials - phenolic resin foaming materials.

Phenolic foam material is a new generation of thermal insulation and sound insulation materials, which are foamed by thermosetting phenolic resin. It has the characteristics of light weight and fireproof, and it is not easy to shrink and embrittle at low temperatures. Since phenolic has a benzene ring structure, it is dimensionally stable and has a small rate of change.

In the production of foaming, Freon is used as a foaming agent, which is fully in line with international environmental protection standards, and is especially suitable for cold insulation of refrigeration and cold storage, petrochemical and other equipment, and the thermal insulation of external walls. Compared with inorganic materials, phenolic foam materials will become a strong competitor in the field of insulation materials.

3. What are the exterior wall insulation materials - foamed cement insulation materials.

Foamed cement was first used in Germany and was introduced to China in 1980. The foaming agent is fully foamed mechanically by the foaming machine, and the foam is evenly mixed with the cement slurry, and then the pump of the foaming machine is cast-in-place for construction. It can form closed foam holes in the concrete, so that the concrete has a good thermal insulation effect.

In addition, the cost of foamed cement insulation materials is low. Therefore, construction projects in China have been widely used.

How to choose exterior wall insulation:

1. Temperature environment.

It is best to choose insulation materials according to the local climate and temperature, such as the northern region, which is colder in winter, so it is necessary to choose some better insulation materials, benzene board is a good choice, and for the south where the temperature difference is not large, it is enough to choose vitrified microbead insulation mortar.

2. Thermal conductivity.

In the case of thermal insulation, it is recommended to choose a thermal insulation material with the minimum thermal conductivity, which is not only convenient for construction, but also takes up space.

3. Stability.

It is better to choose insulation materials with good chemical stability. At the same time, if it is an insulation material for the exterior wall, it is recommended to choose a thermal insulation material with a lower thermal resistance per unit.

4. Mechanical strength.

Exterior wall insulation materials also need to have a certain load bearing capacity and be able to resist external collisions.

Exterior wall insulation materials can eliminate the impact of cold and hot bridges, improve the thermal insulation, moisture-proof and so on of the wall, so many buildings will install insulation materials on the exterior walls of buildings during the construction process. So how many materials are there for building exterior wall insulation? Next, I will briefly introduce it to you.

1. At present, there are many kinds of external wall insulation materials on the market, which can be divided into three categories: inorganic insulation materials, organic insulation materials and composite materials according to the performance of the materials. Inorganic insulation materials include foam cement, foamed ceramics, rock wool, traditional insulation mortar and so on. Inorganic insulation material has excellent temperature and chemical stability, and is non-toxic and non-radioactive environmentally friendly insulation material, which can prevent the generation of cold and hot bridges.

Among them, rock wool has the advantages of good heat insulation, sound absorption, fire prevention, etc., and is the main energy-saving material in the fifth conventional energy source.

2. Organic insulation materials include molded polystyrene board, extruded polystyrene board, phenolic foam, rigid foam polyurethane and so on. The organic thermal insulation material has low thermal conductivity and large thermal resistance value, which can play a good thermal insulation effect, but relatively speaking, its flame retardancy is not very good. Among them, extruded polystyrene board has the advantages of high compressive resistance, strong water vapor permeability, good thermal insulation and flame retardant effect, corrosion resistance, convenient construction and long service life.

3. Composite insulation materials include metal sandwich panels, core materials for polystyrene particles, vitrified microbeads, etc. Among them, vitrified microbeads have the advantages of water absorption, anti-aging, high and low temperature resistance, thermal insulation, etc., which is a lightweight aggregate for making thermal insulation mortar, and improves the comprehensive performance and construction performance of thermal insulation mortar. Metal insulation plywood, usually the core material is usually rock wool and other insulation materials with a certain stiffness, which has the advantages of light weight, easy installation, thermal insulation, high hardness.

There are many kinds of exterior wall insulation materials, they have their own advantages and disadvantages, and we can choose according to our actual needs.
